In the drawings A, represents the standard support, for the work-table a, and the bracket a, which latter is on alower level than the table a, and affords support for the bearing standard a on which the outer end of the power shaft l, is mounted,'-the difference in level between the table a, and said bracket'a', affording accommodation for p, as shown in Figs. 2 and 4. a

The power shaft is also supported in bearings a, a, a, on the table a. An'eccentric p, on said power shaft P, operates the bolt the peripheral portion of the power pulley and'pit-man rod 12 which latter is PIV- otall connected to the said bolt 6. The

' bolt is slidably mounted in'the. standard b aflixed to the table a, and locks the in termittently rotatable transfer member D, while the. punches are doing their'work as hereinafterset forth,the outer end of said bolt protruding at the. proper time into oneof the recesses d, (Fig, 8)- formed for the purpose in the rear disk D, of said intermittent transfer. rotor D, the forward disk D of which'carries the four e uldistant cylindrical blank holders d d f, d, as

showniin Fig. 9. I

By reference particularly to Fig. 21, it will be seen that the intermittent-rotor-member D, is mounted in a box bracket a", secured to the table'a, said box bracket being made in two parts as sho'wn in Figs. 7 and 15, to facilitate the assembling of parts,'and being formed with a sleeve extension a, to

' shield to shed any agglomerate dust escaping from the charge holder; and the rear endv of the hub-d, of this intermittent rotor memaccommodate a shield sleeve d, secured to the transfer disk D and interposed between it and said box bracket (1". The front of the transfer disk D isalso provided with an extension sleeve (1", which also acts as a termittent gearr, which engages with the intermittent gear k aflixed to the constantly rotating drive shaft K." These two intermittent gears i70 and 'r", are shown in detail in Fig. 3,by reference to which it will be 1 seen that the gearv 70 has only one toothed peripheral segment f, while the gear 7'',

has four toothed peripheral segments rh, the intervening spaces 1', being concave and f conforming to the toothless peripheral pitch k, 'of the drive gear i76 Thus .the drive gear will rotate four times to effect a complete rotation'of the intermittent gear 1".

A crank pin 11?, on thepower shaft P, ef-

b by means of the eccentric sleeve 6, (Fig.

fects the reciprocation by means of the pit-' man 10 of the rod C, which carries the its forward end the four armed cross head C. The rear portion 0, of the slide rod 0,

is of angular form in cross section, pr'eferably square, and is mounted in a bearmg standard 0 rigidly secured to the table a,

and having a bearing and cap adapted to the angular cross section of said rearportion 0,

of the rod 0. This structure prevents the turning of the slide rod C, 'on its longitudinal axis and insures'the accurate alinement of the punches E, F G, and H, with relation to the holders d", d d (1*, carried by the 1f)orward disk D, of the intermittent r0- tor The shank e, of the punch E, is rigidly mounted in the socket of the cross head C (Figs. 5 and 10). This punch E, is in reality-a forwarding punch, since its function is to transfer the cylinder of compressed a "glomerate m, from the matrix m, in the mold block M, which latter is rigidly attached to the table a.

The agglomerate is fed in loose form' to the matrix m, through the chute n, which rea ceives the agglomerate in moist condition from the hopper N. Rotatably mounted the latter is the conical feed member N, formed with the radial arms n, which convey the agglomerate to the discharge orifice n ,'in the bottom of the hopper. The dis tance between the adjacent radial arms 41/, prescribes in a degree the quantity of agglomerate for each charge, and the descent of the latter into the chute n, is positively insured by the pusher 9, attached to the lower-end of the rod g, the upper extremity of which is connected with the rock lever g, 1 which isactuated by the rod 9 attached indirectly to the former Q. The former Q, is rigidly attached to the forward end of the arm 9, (Fig. 5) forming part of the vertical 'slide 9 the flanged edges of which rest between vertical ways 9, g", rigidly attached to the table a. The vertical slide g carries aroller 9' (Fig. 15 which rests on the rock lever i, fulcrumed on the standard I; rigidly attached to the'table a.- The rock lever 11, carries a roller 71, which in turn rests upon thecam J, the hub- 51'', of which is mounted loosely on the shaft R, the forward end of which is journaled in the bearing a, on the standard a, (Figs. 2 and 12) also rigidly attached to the table a. A sprlng g", is at tached to the table a, and to the upper part of the vertical slide g, and tends constantly to hold the roller 9', in contact with therock lever z, and the roller 21', in contact with the cam J. The latter is rotated continuously, and is formed to provide for the rest of the lever 71, for about two'thirds of the rotation discharge orifice 11?. The hub j, of the cam J, is formed with a gear j, which derives its motion from the gear 10 affixed to the main drive shaft K, which is in continuous rotation by reason of the engagement of its miter gear is, with the miter gear p, on the power shaft P. The cam gear y'fl, meshes with the gear Z, on the countershaft L, which is mounted in the bearings Z, 1 upon standards attached to the table a. To the front end of the countershaft L, is secured the -crank l, to which is pivotally attached the connection rod 1, also pivotally attached to the ratchet lever 1 carrying the pawll, which engages with the ratchet wheel Z, which is rigidly attached to the rear end of the shaft 1 which is journaled in the hearing sleeve 0, (see Fig. 5) forming part of the bracket 0 which supports the hopper N, saidbracket 0 being rigidly attached to the standard 0 secured to the front of the table is secured the beveled gear Z9, which meshes N; and the rotation of the countershaft L,

is so timed, through the intermediate gearingand connections as to cause a. To the front end of the ratchet shaft i with the 'miter gear 71?, on the lower end of the spindle n, on which the conical feed member N, is mounted, as shown more particularly in Fig, 12. The ratchet Z, has

ig- 12)- to correspond matrix -m,-in the mold-block M; and, the descent of the former Q, compresses the agglomerate w, laterally in the matrix m, as illustrated in Fig. 10, the cylinder of agglomerate thus formed being then transferred by the forwarding punch, E,-

into the cylindrical holder (2', which is in coincidence. wlth sa1d matrix In doing this the forwarding punch E,'forces the rear end. of thejchar e m, against the opposed end. of the solid a utcrank Z congroove I I so that they rotate together while allowmg ment a which is positioned on the front face of the box bracket w ,thereby compress ing the agglomerate charge 00, in the direc-' tion of its length and rendering it more compact and uniform in structure.

As the forwarding punchE, recedes with the cross head C, and other punches mounted thereon, the intermittent rotor D, makes a quarter turn by reason of the quarter turn of the intermittent shaft R, acting through I the action of thecrank p causes the punch ,F, to pierce the charge of agglomerate EX,

centrally, as illustrated in Fig. 17, to form an axial socket or hole for the reception of the carbon pencil or core as, (Fig. 18) the displaced and discarded matter of, left in the bore a, 'by the preceding operation being ejected through the hole a, in the hol- "low abutment-a, which however otherwise sustains the agglomerate charge m, in the holder 01. Like the abutment a the abutment at, is positioned on the face of the box bracket a, and, it is formed not only with the axial bore a, but also with the outlet a, for the escapeof the discard m The piercingpunch F, is mounted in a shank f, .secured to a rotatable hub f, journaled in the socket 0,of the cross head C, as shown in Fig. 16, said hub f, being rotated by means of a sprocket chain f engaging sprocket teeth on the hub f, of said punch F, and also engaging sprocket teeth on a hub f rigidly secured to the rotatable.

shaft f. This shaft f, is mounted in and between a bearing 0 integral with the socket 0 and a bearing a", forming part of',

standard a. The key f, and longitudinal couple the sleeve i and shaft f,

the shaft f, to slide longitudinally in said sleeve f. On the rear end of said sleeve f,

is rigidly attached the sprocket-wheel f,

which is connected by the sprocket chain 7, with sprocket teeth on the hub j, of the cam J Thus thecam J, and the shaft f, travel together at the same rate of. speed, and transmit the same'speed and motion through the medium of the sprocket chain f, to the F. By thus I spindle f, of the piercing punch rotating the piercing punch F, it works its way through the agglomerate charge as,

ateral bend or devia- 'without any dan er of and also may be tion from true a inement;

. fi, (see Fig. 20) in the sleeve f, which is ,mounted in the bearing a", of the bracket Withdrawn with much less danger of chipping or breaking theperforated charge.

I medium of the gears'r, k, and d carries the holder d, into coincidence with the placing punch G, (see Figs. 27, to 29, inclusive) by which the carbon pencil-or core m, (Fig.

18) is inserted in the axial bore or hole just formed for it in the bobbin or cylinder 00.

The carbon cores m, are fed to the axial pocket 9, in the sleeve '9', in which the forwarding punch G, operates, from a hopper S, which is rigidly supported uponthe bearing sleeve forming the top of the standard a, which is rigidly attached to the bracket a ,'which forms a forward extension of the table a, (see Fig. 4). The sides as shown in Fig. 12, so as to feed the carbon cores m, by gravity-to the central exit port 3, at the bottom of the hopper, through which exit port s, -the cores :0, descend, one by one, into the pockets of the feed Wheel 8'', which is mounted upon the forward end of the shaft 8. which is journaled in the aforesaid bearingsleeve a, of the standard 0, (Figs. 4, and 15) the rear end of said shaft s having-rigidly-attached to it the ratchet wheel 8 which 1s actuated by a pawl 8, pivotally supported between the twin rock levers s, .9, (see Figs. 4:, and '8) fulcrumed on said shaft said rock levers s .3 being oscillated by means of the pitman s, to which they are pivotally connected, and said pitman 8", being reciprocated by reason of its pivotal connection with'the crank-sprocket wheel 8', rigidly mounted on the rear end of the shaft 8 (Fig. 8) which is journaled in the bearing sleeve 0,, on the end of the extension arm a, of the bracket a", which is rigidly secured to the top of the box bracket '11", as shown particularly in Fig. 15. 1 a

The crank-s. rocket wheel 8", is connected by a sprocket c ain 3,with the sprocket wheel on the sleeve i of shaft f, which is slidably mounted, as hereinbefore stated, in said sleeve 1", and the bearing a", on said standard a. Hence the shaft 8 rotates in s rocket chain f, which, engages with the s eeve' sprocket f, andwith the sprocket teeth in the hub 7', of the cam J. Since the cam J, makes one rotation for each rotation of the power shaft P, as hereinbefore described, it is obvious that through the means of the intermediate sprocket wheels and chains, the shaft 8 and crank sprocket 8 will also rotate once for each rotation ,of the power shaft and hence the pitman s, will rock the pawl levers 8,- once during that period causing the aWl 8, to advance the ratchet wheel 8 su ciently to release a carbon core :0, from the hopper.

' The latter are thus delivered successively t the inclined Way 8 by which they are dellvered, if perfect, to the axial ocke g, in the sleeve 9' mounted in the fixed bearing 8. If broken or imperfect they drop from the feed wheel 8, through the relief exit 8, into a receptacle s provided for the pmpose. The relief exit 8", is shown in cross 1 detail-in Fig. 14, in which a perfectcore is shown in dotted lines as bridging the opening s", with-its ends resting on the edges thereof, while in solidlines a defective core is shown as making its exit through said opening. 4

As only one core as, is released fromfthe hoppers, at. each quarter turn of the carrier 7 disk D ,'the inclined way 8 is of such of this hopper S, are inclined Convergently,

length as to accommodate a sulficient numberof cores to compensate for any broken or defective cores dlscarded as above stated. That is to say there is always a surplus of cores on said feed way 8 the lowest core -in the column resting in the axial groove 9,. with the others in'alinement above it.

When the punch G, advances it encounters the lowest core, that in theaxial groove and causes the latter to push the last prece ing core into the bore or hole in the tubular cylindrical charge in the holder d, as shown in Fig. 28. At this point the head 0*, of

The continued advance of the crosshead C; presses back the sleeve-g, against the resistance of the spring 9, pushing the core m, farther into the bore of the apertured cylindrical charge an, as shown in Fig. 29, and bringing the tip' 9, of'the charge presser 9, into contact with the outer end of the char e of 'agglomerate m. At the same time the tip a", of the abutment a, is advanced into contact with the other end of said charge :17, the two tips 9 and a", exerting I an.endwise pressure thereon and compressin it longitudinally.- 4

uring this endwise pressure on the charge in, both nipples or tips a 'and 9 are partially rotated on their axes forthe purpose of smoothing the ends of the charge and preventing the material thereof adhering to said nipples when they are withdrawn.

The stem of the charge presse g, is. threaded to engage with a female screw thread formed for it in the sleeve g, and its partial rotation is effected by means of a p1tman sf, pivotally connected with an arm; g", (Fig. 24) of the core presser g, and with the crankdisk 8 (Fig. 12) 'on the front end of the shaft 8 L tial rotation of thecore presser g, not only 0 twists-the face; of thenipple g, in contact with the end of the charge 00, but also, by g reason of its screw connection with the sleeve 9', causes said nipple g", to compress the charge longitudinally-as before stated 15 with the opposed nipple a", of the abutment 0 as apointof resistance. i The corresponding partial rotation of the l I abutment 0: 9, is effected by means of a pitr man a ,-pivotally connected to an arm a,

on the shank or spindlea of said abut- -.ment a the upper end of said pitman a,

being connected with the strapof an eccentric a on the shaft 8 eccentric 0", causes the pitman a, to rock is the abutment a against the resistance of the spring a, (Fig. 22) interposed between a nut collar a, on the end of the spindle a and the bearing sleeve a, rigidly secured to the boxbracket a, and within which 0' said spindle shank a is mounted. This T 8 It, tends constantly to draw' the a utment a", back with. its radial pin'a, in contactwith the cam surface at", on the bearing sleeve a", as shown more particularly in Fi 22, and 23., and to hold said a a, at t e rear end of said cam surface.

uswhen the eccentric a, raises the pitman a", the pin a, will be forced u the cam surface a", against the resistance of 40 saidsp'ring a, thereby not only rocking. the nipple a", to twist its surface in contact with the rear .end of the, charge of agglomerate w, a but also advancing sai nipple a", 'so that 1- it compresses the agglomerate charge an, endwise against the resistance of the opposed nipple.g ,'on the charge-'presser 9', eithe sleeve 9', as shown in Fig; 29.

'mounted in a bearing sleeve 0, supported adjustably in'a bushing 0 rigidly secured n to the socket 0 of the cross head C. Said shank g", is formed with a male thread g, I, engaging a female thread formed for it in said bearing sleeve 0. Said shank g, is also provided with a handle 9, 'or equivalent by which it may be turned to regulate the extent of protuberance of the plunger G. A set screw 9, may be used to secure the shank g", in prescribed position.

7 The bearing sleeve 0, is also. formed with 5 a male screw thread a, engaging with a female thread formed for it in the bushing 11, so that the said sleeve 0, maybe adjusted in said bushing c, to regulate the protuberance, if any desired, of its inner end 9, beyond the inner end of said bushing 0 for the purpose of prescribing the op-' erative thrust of the socket a, as related to the forward end 'of the extension 9, of the sleeve g, and thereby regulating the inward 9 5 thrust of said sleece g, as related to the transfer disk D, and holders 'mounted thereon. Thus the extent of longitudinal compression exerted against the charge of agglomerate 00, may be prescribed with accuracy according to the density and compactness required, as well as also a desired predetermined length of the finally compressed charge. p

. We have herein shown and described our 5 apparatus as adapted to the automatic man.-

ufacture of carbon elements for dry batteries, etc. By its use as compared with the old method of production by hand labor, we

greatly reduce the cost of manufacture and attain a better and more perfect product, in

that it is more compact, homogeneous and uniform in shape and structure, and hence oflonger life and efficiency. 7 V

' But essential features of our invention 116 and apparatus are applicable" for the manufacture-of other products, formed from comminuted material, such cakes or briquets for various purposes-,so that we do not wish to restrict ourselves to the manufacture of bat- 120 tery carbon elements exclusively. It is obvious that various modifications may be made in the construction shown in the drawin and above particularly described withm the principle and scope of our I invention.
